Anotherohject oi the, invention is to provido attachments for thetrector which can be readily fastened to it in such a marines that; the parts are substantially supported and carried by the tractor, without any material alteration of the tractor parts. 1

A further object of the invention is to provide a cultivator and accessories which can he entirely supported on the tractor drawbar and differential housing.

A; further object of the invention is'to provide simple and substantial attachments for extending the tractor driving and steering mechanisms back Where they will be accessihle to the driver seated over the cultivator I Further objects and details of the invention will appear as described in connection with the accompanying drawings, and hereinafter set forth and claimed. I

In the drawings illustrating the invention:

Figure l. is a plan View showing the rear cnd are tractor having cultivator attachments connected therewith,

Figure 2 is a side elevationof the same,

' and Figure is an elevation of a detail.

The tractor, parts of which are shown in the drawings, represents one of the small types of tractors propelled by an internal combustion engine, and is designated generally by the reference numeral 10. The rear axle and diii'erential housing 11 extends between the wheels 12 of the tractor, and the transmission casing 13 extends forwardly from the dili'erential housing to the engine, front wheels, etc, (not shown). The fuel tank is shown at 14; drawbar on the rear of the differential housing 15; steering column, 16; throttle control, 17; clutch.release, 18; and gear shift 19.

The plow beam and frame member 20. is adapted to be bolted or otherwise fastened to the-tractor draivbar if). ltcomprises a 21, by means of two way clevises, 29 and 30.

These clevises have ivotal connections with the plow beam whic 1. permit them to swing in and out whereby they may be moved horizontally, and the drag bars of the cultivators are also pivotally connected with them in a, manner allowing vertical movement for raising and lowering the cultivators. The cultivators are shown provided with stivrups 31, so that the operator, seated over them, n' ay guide them with his feet.

Positioned on the outer ends of the supporting members, 22 and 23, are operating levers, 32 and 33, for adjusting the drag bars of the cultivators so they can be raised or lowered. As best shown in Figure .2, lcyer 33, is pivotally mounted. on the supporting member 23'; its lower end is connected with link 34, which has a spring supporting connection 35 with the drag bar '27. A ratchet segment 3(, is mounted on the supporting member 23, and a spring pressed pavil 37, on lever 33, cooperates therewith for holding the lever in its adjusted position. At the upper end of the lever are handles 38 and 39, for operating the lever as desired. Lever 32, on supporting member 22,-is constructed in a similar manner.

The scat l0, which may be the original tractor seat, which had been mounted over the dillercntial housing, is mounted in the proper position for the driver on a [channel iron seat supporting bar ll. This bar; is bolted to the differential housing at i4t2, and to the transmission and engine casing at 4:3. 'The steering wheel, 44, may also be the original steering wheel removed from the top of the steering column 16, mounted on a supplemental steering rod to, extending back so the driver can manage the wheel from his seat. A bevel gear 46, replaces the steering wheel on the steering column 16, and a second bevel gear 47, is positioned on the steering rod and meshed with gear 4:6. A. casing 48, forms ahousing for these gears holding them in mesh, and forms a. supporting bracket for the extension steering rod 45.

A casing, 49, is provided for the connection hetween the throttle control rod 17, and throttle extension rod 50, which has a handle 51, accessible to the driver. The connection between these throttle controlling rods may he u hevcl gear drive within the casing 49, lo similar to the steering rod connections.

A support 52, for the supplemental steerlug rod 4 5. and throttle extension rod 50, is mounted on the ditlerential housing in u similar manner the supports 24- und 25,

ure, by one-oi the holts for holding the housiug together. By means of this support und thecasing 4-8 and 49, these rods are secured.

in proper position for operation by the driver in seat 10. i

In a similar manner the clutch release lever 18, is extended back by means of e rod 52, so as to be within reach of the driver for operating the clutch \vitilneitherthe foot or the hand. This rod is mounted in u. guide 53, on support 25, midway of its len la. An

extension rod 54, is likewise provided for operotinir the gear -shift from thedrivefs seat, and extends through a guide 55, on the sup ort 24-. 'l is embodiment .of the invention herein disclosed is specifically e cultivator adopted 't'ornse with small plants, vegetuloles, etc, which the tractor will readily pass over. However, forcultiveting Where more clear- F once is needed, special rear wheelsme be i used and e. front uxle 56, having its ends lient downwardly to allow for clearance, may be substituted for the straight front axle; the steering connecting rod and radius rod are also bent to allow for clearance inthe some manner.
